OF THE COUNTY OF LANCASTER, ENGLAND. I

MACHINE FOR TAKING COPIES OF WRITTEN O R PRINTED MATTER.

SPECIFICATION forming part of Letters Patent No. 425,651, dated April 15, 1890.

Application filed June 21, 1888. Serial No. 277,728. (No model.) Patented in England August 31, 1887, No. 11,806.

To all whom it may concern.-

Be it known that I, WILLIAM BLAND, a subject of the Queen of Great Britain, residing at 24 Berners Street, Leicester, England, have invented new and useful Improvements in Machines for, Taking Copies of WVritten or Printed Matter, (for which I have obtained a patent in Great Britain, No. 11,806, hearing date August 31, 1887,) of which the following is a specification.

This invention relates to a novel construction or arrangement of apparatus by which copies of writings, printings, designs, or devices drawn or otherwise prepared on ordinary paper with aniline ink and transferred onto a gelatinized paper or parchment may be printed upon ordinary paper in black, blue, or other color, fac-simile copies being produced.

The apparatus forming the subject of this invention is composed of two side frames arranged at a given distance apart by tie-rods and carrying orsupporting four rollers and a table, on which the papers to be printed are led into the apparatus, the sheets of paper being gripped by one of the rollers and drawn through the machine from between two of the other rollers, one of which gives the desired pressure, and the other has a transfer of the original writing or device upon a gelatinized paper wrapped around it. The fourth or inking roller is situated at the back of the apparatus, and during a portion of the rotation of the transfer-roller the inked surface of said inking-roller is forced out of contact with it by segmental ribs on the transferroller, so that only that portion of the transfer-roller on which the gelatinized paper is wrapped can be inked, said inking-roller being pressed back again into position for that purpose by springs. The hand-wheel, by which the transfer-roller is rotated, carries a cogged wheel with a portion of the teeth removed, so that when said plain portion is passing the teeth of the paper-drawing roller said paper-drawing roller stands idle. is also the pressure-roller, is carried on the end of a pivoted frame and can be raised and lowered by a hand-lever, the boss of which has a cam-groove for a pin of the pivoted The feed-roller, which frame to ride in. The roller on which the gelatinized paper or parchment is placed is slotted radially, and gripping-plates, to which the two ends of the gelatinized paper are secured, can be forced down these radial slots and secured for keeping the gelatinized paper in a stretched, even, and firm position for the proper printing operation to be performed.

The annexed drawings show the invention.

Figure 1 is a plan of a complete apparatus. Fig. 2 is a side elevation of the left-hand side of the apparatus with the hand-wheel partly removed to show the hit-and-miss portion of the gear-wheel. Fig. 3 is an elevation of the left-hand side of the several rollers with the side frame removed. Fig. 4 is an elevation of the back of the apparatus with a portion of the lower or paper-drawing roller removed. Fig. 5 is a perspective sectional view of the lower or paper-drawing roller, illustrating the connection of the gripper-plate with its oscillatory shaft. Fig. 6 is a sectional elevation of the roller on which the gelatinized paper or parchment is stretched, and Fig. 7 is a perspective view of a trough for receiving one end of the gelatinized paper, Fig. 8 showing a bar capable of being pressed into the trough Fig. 7 and be fixed in position by swivelplates.

All letters of reference denote the same parts.

A A are the two side frames of the apparatus. B B are the tie-bars, which hold said side frames at their respective distances apart.

C is the gelatinized paper or parchment carrying roller. D D are radial slots in said roller, into which the trough E and bar F, Figs. 7 and 8, are inserted when the gelatinized paper or parchment is stretched around the roller C, the trough and bar (of which o there are two) being rigidly fixed by fly-nuts G G.

H H are swivel-plates, which look the bar in the trough and rigidly fix the end of the gelatinized paper or parchment therein.

The roller C is covered with oil-cloth or other slightly-yielding fabric over which the gelatinized paper or parchment is stretched. The axle I of the roller 0 has on one end a hand-wheel J, and the inner face of this is roe provided with teeth J for, say, three-fourths of a circle, the other fourth being plain in order to escape the teeth of the gear-wheel K, which is upon the axle L of the lowerroller M, by which the paper while being printed is drawn through the machine. Within this roller M is a shaft N, which receives an oscillatory motion through a lever P on its end striking a pin Q, projecting from the inside of the left-hand side frame A, the motion of which lever tilts a gripper-plate R and allows each sheet of paper as fed into the apparatus to pass under said plate R and against the stationary roller until the teeth on the handwheel I again gear into the wheel K, which motion forces the lever P away from the pin Q, the plate B. being simultaneously pressed onto and caused to grip the paper under the pressure of the spring 8..

T is a roller, of soft material-say indiarubberwhich is carried on the inner end of a frame U, pivoted to the two side frames Aat V, and provided at its outer end with a pin h,

* that is engaged in the cam-groove m of a rotary boss W, having a hand-lever Y, which roller T, when the frame U is pressed downward at its outer end by the cam boss W through a motion of the hand-lever Y, comes into close contact with the roller 0, and exerts sufficient pressure for the transfer of the ink from the gelatinized paper or parchment onto the sheet of paper passing through the apparatus, the ink having been supplied to the gelatinized paper or parchment by the inking-roller Z. It is obvious that the pressure exerted by the roller T will be determined by the degree of the movement given to the hand-lever Y in actuating thecam-boss IV, that is engaged with the pin 71. in the end of the frame U, in which said roller is mounted.

a a are ribs on the periphery of the roller 0, which, as the roller (3 is rotated, press against collars b of the inking-roller Z to force it away from the roller 0, so that that part of the gelatinized paper which has not been written on should not be inked, the inking-roller Z being returned for inking purposes by the side springs c c as soon as the ribs a have passed the collars b.

The oscillatory frame U has a top plate d, on which the ink to be employed for printing is first spread or distributed, and on which the roller Z may be rolled for receiving its supply; or said roller- Z may have printingink distributed on it by an extra roller being put in contact and by turning a small handle e.

f is another plate, which can be dropped onto the oscillatory plate U and form a surface or table onto which the papers to be printed can be placed.

What I claim is-- 1. In a transfer copy-printing apparatus, the combination, with a pressure-roller, of the radially-slotted transfer-roller 0, provided with troughs E and bars F, substantially as and for the purpose described.

2. In a transfer copy-printing apparatus, the combination of the grip-roller M, having a shaft L, provided with gear K, the transferroller 0, having a shaft I, provided with mutilated gear J, the inki ng-roller Z, and the pressure-roller T, substantially as described.

3. In a transfer copy-printing apparatus,

the combination, with the transfer-roller C, of the pivoted frame U, having the pressureroller '1 mounted in one end and provided at its other end with pin h, and the cam-grooved boss W, provided with a hand-lever Y, sub-
